Accupro ACC-BBL320750 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL320750 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with a bright finish coating, it delivers tight dimensional control in small-bore applications. The left-hand cutting direction suits specific spindle orientations and back-boring setups. With a 3/8 inch shank diameter and a 2.5 inch overall length, this bar fits compact tooling blocks and quick-change holders common in production turning environments. It is suited for machinists and toolroom operators working with close-tolerance bores in ferrous and non-ferrous materials.

This boring bar is used in production machining and toolroom settings where small-diameter internal features require accurate, repeatable cutting. The 0.32 inch minimum bore diameter and 0.75 inch maximum bore depth make it appropriate for short, tight-tolerance holes in turned parts. It is a practical choice for job shops, aerospace component manufacturers, and precision parts producers running left-hand turning operations on CNC or manual equipment.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance in small-bore cutting
• Left-hand cutting direction for back-boring and specific spindle orientation applications
• 0.32 inch minimum bore diameter supports tight internal feature work
• 0.75 inch maximum bore depth suits short-bore production applications
• Bright finish coating on the shank for easy visual inspection and tool identification
• 3/8 inch shank diameter fits standard small-bore toolholders and quick-change systems

Compatibility

Designed as an OEM-style replacement and direct-fit boring bar for standard 3/8 inch shank boring bar holders used in CNC and manual turning applications requiring left-hand cut geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine before seating or removing the bar from the toolholder. Confirm shank clamp torque against the toolholder manufacturer specifications before cutting. Verify cutting direction matches spindle rotation before initiating any cut to avoid tool damage or workpiece scrap.
